Honestly, him dying is very real concern to me. If Republicans keep the House and he passes away, I can certainly see somebody trying to do something to Kamala Harris, as the Speaker of the House is next in line after the Vice President.
That said, I’d vote for Joe Biden if he was fucking 110, if the other option was Donald Trump. Or any Republican honestly.
If only so I can see how they get him/her inside Air Force One, yes.
